我改成如下代码,也不行, 问题是我根本就没有去碰bsasa这个combobox 控件,为什么会激发这个事件呢 private void bsasa_MouseLeave(object sender, EventArgs e) { string sbe = bdate1.Value.ToShortDateString(); string sen = bdate11.Value.ToShortDateString(); sdc2.cleardt(); string ssq3 = "select a.socode as 订单号,c.str2 as 客户,a.saleb as 合同号,a.salec as 销售类型,a.date2 as 交期,a.date4 as 线材完成日期,a.date3 as 成品完成日期,a.saled as 注意项,a.re1 as 备注," + "b.sasa as 客户型号,b.inta as 项次,b.cinvcode as 编码,b.cinvname as 品名,b.cinvstd as 规格,b.intb as 数量,b.sasb as 单位," + "b.sasc as 材质颜色,b.sasd as 连接器,b.sase as 印字,b.sasf as 接法及备注,b.sasg as 包装要求 " + "from Dsale a left join Dsaleson b on a.socode=b.socode left join Dcustomer c on a.salea = c.codestr " + "where b.sasa = '" + bsasa.Text + "' and a.date1 between '" + sbe + "' and '" + sen + "' "; dataGridView1.DataSource = sdc2.adt(ssq3); }
private void bsasa_MouseLeave(object sender, EventArgs e)
{
string sbe = bdate1.Value.ToShortDateString();
string sen = bdate11.Value.ToShortDateString();
sdc2.cleardt();
string ssq3 = "select a.socode as 订单号,c.str2 as 客户,a.saleb as 合同号,a.salec as 销售类型,a.date2 as 交期,a.date4 as 线材完成日期,a.date3 as 成品完成日期,a.saled as 注意项,a.re1 as 备注," +

dataGridView1.DataSource = sdc2.adt(ssq3);
}
看名字就知道是鼠标事件,和MouseMove,MouseEnter一家人的
也就是说只要鼠标移过(离开)那个控件就会发生
并不是像你“本以为”的那样
